This is an engine replacement kit for the Walker MTGHS zero turn riding mower. It is offered with either a new Kohler Command ECH749 or a new Honda GX690, and it includes what is needed to convert the mower from the old engine to the new one, unless otherwise stated.
The Honda kit comes with a new engine, driveline adapters, exhaust, mounting accessories and an electrical harness. The engine has a 3-year commercial warranty. Replacement engines come with a standard dual-element air cleaner. EPA regulations require the new engine to be operated with the stock air cleaner.
The Kohler ECH749 uses sensor technology and Closed-Loop technology to adapt to operating conditions. It has no carburetor, no choke and no priming, and it starts with a key. It has a 3-year unlimited-hour commercial warranty. The Honda GX690 has a two-barrel inner-vent carburetor, a hemispherical combustion chamber, a forged steel crankshaft and pressure-fed crankshaft bearings. It also has a high-capacity oil pump, a large-diameter air intake and a high-efficiency cooling fan.
